Abstract
A synchronous semiconductor memory device according to the present invention includes a memory array circuit for performing reading/writing of data sent to or received at a data terminal with respect to a memory cell array; a write data retaining circuit and a write address retaining circuit for temporarily retaining write data and addresses corresponding to the write data, respectively; an address matching circuit for performing matching of an input address with addresses stored in the address retaining circuit; and a data path select circuit for outputting the write data temporarily stored in the write data retaining circuit to the data terminal according to the matching result. The address matching circuit is disabled during a clock cycle in which a writing operation is designated.
